Overview
Low profile, ease of operation, high-efficiency screed plate heating systems, low-maintenance screed plates and superior serviceability are combined to provide a superior screed, the AS3301C. The AS3301C offers a diesel screed plate heating system or an electric screed plate heating system. Both systems are highly efficient and provide fast warm-up.

Benefits & Features
Screed Plates
Precompaction And Material Flow
Curved nose bar design provides precompaction and enhances material flow under the screed.
Nose Bar And Screed Plate Replacements
Nose bar and screed plate replacement are simplified with tapped holes and studs.
Heavy-Duty Mounting Platform
Heavy-duty mounting platforms provide rigid support for screed plates, which simplifies leveling.
Screed Plate Leveling
Extra Corrosion Resistance
The trailing edge adjusting bolt system hardware is plated to provide extra corrosion resistance.
Spring-Loaded End Gates
False-Wall End Gate Design
False-wall design reduces mix contact with the sliding portion of the gate, providing easy gate adjustments.
Bolt-on End Gate Design
Bolt-on design allows easy end gate installation and removal.
Replaceable Wear Strip
Replaceable wear strip enhances end gate service life.
Full-Length End Gate
Full-length end gate contains material, providing an optimal longitudinal joint.
Triangular Extender Configuration
Visual Graduated Scales
Visual graduated scales indicate the distance that the extenders move in or out.
Hydraulically Driven Vibrators
Hydraulically driven vibrators located on the extenders are synchronized with the main screed to match frequency and amplitude.
Vertical Height Adjustment
Vertical height adjustment allows the extenders to match the main screed height.
Electric Screed Plate Heating System
Multi-Zone Heating Element
Multi-zone heating element configuration provides even heat distribution.
Screed Control Panel
Screed control panel includes three temperature settings that are able to accommodate normal hot mix asphalt and extended temperature based mixes.
Regulated Screed Plate Temperature
Controller automatically regulates the screed plate temperature to the selected setting.
Minimal Operator Training
On-board diagnostics and screed control panel require minimal operator training.
Serviceability
Hydraulic Hoses And Electrical Wiring
Hydraulic hoses and electrical wiring harnesses are cleanly routed and clamped to reduce wear and provide easy service.
Remote-Mounted Fittings
Remote-mounted fittings for vibrator bearings provide simplified lubrication access.
Reliability
O-Ring face seal fittings and couplings provide maximum protection against hydraulic leaks.
Nylon Sleeve Protection
Exposed hoses have nylon sleeve protection to reduce abrasion.
Vibrator System Hydraulic Lines
Vibrator system hydraulic lines are constructed of steel tubing, providing durability and resistance to damage.
Electrical Standards
The Cat® electrical standards, developed to enhance reliability and durability, feature soldered, molded, numbered and color-coded wires. Nylon-braided wrap protects the electrical wires.
Electrical Schematics
Electrical schematics detailing wire numbers, wire colors and component part numbers are located in the service manual.
